While a bit pricer than some, you can’t go wrong with a Fort Knox (www.ftknox.com). I know you’re not interested in the “General Yeager” series ($$$$$!), but they have some economy models with impressive features. Unfortunately, I don’t know the prices nowadays.
If you’re in the Northern Virginia area, there’s a Fort Knox distributor who has a setup at most local gun shows. (My recollection is that he’s Steve’s something or another out of Vienna. However, he doesn’t have a store, he works out of his house.) The Fort Knox website has a 1-800 number, so I’m sure you could track down a distributor through them.
Liberty safes are also pretty good; just stay away from the really low end ones. Treadloc is also good (and made in Virginia); however, their safe walls are a little thin. Browning is ok but, to my mind, a little overpriced for what you get (actually, I think their safes are made by Gardall). I’m not a big fan of American Security but I’m only really familiar with their older safes; their newer ones seem to be better.
Things to think about:
How much weight can your floor handle (to include the safe’s contents)?
Fireproofing keeps the safe’s internal temperature down. It also makes the safe heavier and more expensive. Fireproofing takes up a small amount of room in the safe.
Often the same safe is available with different interiors. If you’ve got a lot of handguns, you’ll probably want an interior with lots of shelves. Lots of rifles will require a different layout. Assuming the vendor is willing to do it, interiors are easy to special order since they essentially drop into the safe.
Usually, safe doors have the hinges on the right and open from the left. You can special order one with the door reversed, if you need to.
Do you care if the hinges are internal or external? Fort Knox, for example, uses internal; Browning uses external. Internal look a little nicer and are protected from attack. However, they intrude into the safe a bit. External hinges save internal space and allow the door to open wider. (External hinges aren’t really a point of attack either since there are – or should be! - internal bolts on that side of the door which hold it closed even if the hinges are destroyed.)
Incidentally, you can move the safe on a flat floor fairly easily by rolling it on short pieces of PVC tubing – something like the Egyptians did when building the pyramids.
If you want to do some serious comparison shopping based on features, I’d be happy to put together a list of things to look for. However, this gets complicated fast. Good luck!!
